Abstract

PURPOSE:To increase the gloss of image receiving paper by once uniformizing the unevenness of the image receiving paper in the lateral direction thereof by a mat surface roller and successively applying a sliding surface roller to said paper. CONSTITUTION:Image receiving paper 19 having an image recorded thereon by thermal transfer is inserted from an insertion port 11 while the image receiving surface 19a thereof is turned upwardly and respectively heated by heaters 21, 22 through a mat surface roller 13 and a press roller 14. By this method, the image receiving surface 19a is softened and the image receiving paper 19 is fed while the image receiving surface 19a is pressed to the mat surface of the roller 13 by the press roller 14. Therefore, the image receiving surface 19a is made mat corresponding to the mat surface 18. The rotation of both of the mat surface roller 13 and the press roller 14 is continued and the image receiving paper 19 passes on a guide plate 31 to reach a sliding surface roller 16. The image receiving surface 19a is cooled to be hardened during this time and again heated by heaters 24, 26 to be softened. The image receiving surface 19a made mat is smoothed by the sliding surface roller 16.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a print glossing device that glosses the surface of image-receiving paper on which images, characters, etc. are recorded.

[Prior Art] In image recording using a thermal transfer printer, when the dye on the ink ribbon is heated by a thermal head and transferred to image-receiving paper, the image-receiving surface of the image-receiving paper is softened by the heat of the thermal head, and the dye on the image-receiving surface is Irregularities occur depending on the presence or absence of printing. To deal with this, a print surface glossing device (
JP-A-62-132680) is known. In this device, in order to make the surface of the image receiving paper glossy, a heating roller with a built-in heater is placed close to the outer peripheral surface of the platen, and the surface of the image receiving paper is heated and pressurized after recording to make it glossy. .

[Problems to be Solved by the Invention] However, since the above-mentioned apparatus can only perform glossing processing on the receiving paper, in order to make the receiving paper matte and give it a matte finish, a separate device or a roller or the like must be used. It was necessary to replace the parts, and the work of inserting the image receiving paper into a separate device and replacing the parts was troublesome. In addition, when smoothing image-receiving paper, simply running it once on a smooth roller cannot sufficiently smooth out the many irregularities corresponding to the print density, especially in the width direction of the image-receiving paper (perpendicular to direction), there was a tendency for unevenness to remain.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a Bling 1 glossing device that can perform both glossing and matting processing without using a separate device or replacing parts.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a matte surface roller that makes the surface of the image receiving paper heated by the first heating means matte, and a matte surface roller that applies the image receiving paper to the matte surface roller. A first pressure roller that presses, a second heating means that heats the image receiving paper that has been made into a matte surface and is sent to the first path, and a smooth surface roller that smoothes the surface of the image receiving paper heated by the second heating means. and a second pressing roller that presses the image receiving paper against the smooth roller;
A print glossing device is constituted by a means for distributing the matte-surfaced image receiving paper to a second path that avoids the smooth roller or to the first path.

Further, when the first switch is turned on, a first heating means for heating the image receiving paper, a matte surface roller for making the surface of the image receiving paper heated by the first heating means into a matte surface, and a matte surface roller for converting the image receiving paper into a matte surface. a first pressing roller that presses the
When the second switch is turned on, a second heating means heats the image receiving paper that has passed through the matte surface roller, a smooth surface roller smoothes the surface of the image receiving paper heated by the second heating means, and a smooth surface roller. It is also an effective solution to configure the print glossing device from a second pressure roller that presses the image receiving paper against the image receiving paper.

[Effect]

According to the former method, when performing the glossing process, it is possible to distribute the image-receiving paper that has been made into a matte surface by a matte surface roller to the first path, and further to perform a smoothing process using a smooth surface roller. can. According to this, since the unevenness in the width direction of the receiving paper has been made uniform by the matte surface roller, the smooth surface roller is applied again, so that even more beautiful gloss can be achieved. On the other hand, when the paper is distributed to the second path, it becomes possible to obtain image receiving paper that has been subjected to matte surface treatment without passing through the smooth roller.

Further, according to the latter, when the first heating means heats the image receiving paper by turning on the first switch, the surface of the image receiving paper is softened, and the entire surface treatment of the image receiving paper is enabled. Furthermore, by turning on the second switch, the second heating means heats the image receiving paper that has undergone the matte surface treatment, thereby enabling the smoothing treatment. If you do not turn on the second switch here,
Since the surface of the matte-treated receiver paper is passed through a smooth roller while being hardened, it is not smoothed and is therefore not matted.
・It is possible to obtain surfaced image-receiving paper. Furthermore, the device may be operated without turning on the first switch if necessary.

Embodiments of the present invention will be described below with reference to the drawings.

〔Example〕

In FIG. 1 showing the cross section of the glossing device according to the embodiment of the present invention, there is a U
A glyph processing path 12 is provided. Along the processing path 12, a matte surface roller 13 and a pressure roller 14 opposed thereto are arranged near the insertion opening 11, and a smooth surface roller 16 and a pressure roller 15 opposed thereto are arranged at the back. [Masotho surface roller] 3 is a roller having a matte surface 18 with minute irregularities formed on its outer periphery, and its axial length is set to be longer than the image receiving paper 19 to be inserted. The pressing roller 14 is also a roller having the same shape as the man 1/face roller 13, and presses the image receiving paper 19 against the face 18 by a biasing member (not shown). Matte surface roller 13, pressure roller 14
The heaters 21.2 are arranged close to each other above and below.
2 has the same length as the rollers in the axial direction of both rollers, and can heat the rollers evenly. In this way, the heaters 21 and 22 indirectly heat the image receiving area 19 by heating the matte surface roller 13 and the pressing roller 14.

The smooth surface roller 16 is a roller having the same shape as the matte surface roller 13 and has a smooth surface 23 arranged on its outer periphery.

The pressure roller 15 also has the same shape as the matte surface roller 13. Similarly to the above, the heaters 24 and 26 are connected to the smooth roller 16.
．． To evenly heat a pressure roller 15. four heats 2
1, 22, 24, and 26 generate heat when a power switch (not shown) is turned on. Further, discharge port rollers 27 and 28 disposed in the rear half of the processing path 12 are rollers for conveying and discharging the image receiving plate 19 that has been processed. The receiving paper 19 is discharged from a discharge port 29 at the end of the processing path 12 by a discharge port roller 28 . These discharge ports 28, 29 and the above-mentioned 4
Each of the rollers 13 to 16 rotates in the receiving paper feeding direction when the power switch is turned on.

A guide plate 31 disposed between the matte surface roller 13 and the smooth surface roller 16 constitutes the lower surface portion of the processing path 12 within the illustrated range, and is formed longer than the image receiving plate 19 in the width direction of the image receiving paper 19. There is. The guide plate 31 is pivotally supported by a hinge part 32, and normally takes the position shown by the solid line by a spring provided in a solenoid 33, but when the solenoid 33 is driven and energized, it moves against the bias of the spring. It is rotated by a predetermined angle and takes a position 31a (not shown by the broken line). Thereby, the matte-surfaced image receiving paper 19 can be guided to the high-pass path 34. The solenoid 33 at this time is controlled by switching the switch 36.

Hereinafter, the operation of this embodiment configured as described above will be explained.

First, turn on the power switch and turn on the heaters 21, 22, 24.
．． 26 and rollers 13 to 16, 27, and 28.

Then, the switch 36 is used to select smoothing processing or matte processing. For example, if smoothing is desired, switch 36 is placed in the upper position. At this time, solenoid 33
Since the guide plate 32 is not driven, the guide plate 32 maintains the solid line position.

Next, the image receiving paper 19 on which the image has been recorded by thermal transfer is inserted through the insertion slot 11 with the image receiving surface 19a facing upward. The image receiving area 19 is heated by the heater 21 via the matte surface roller 13 and by the heater 22 via the pressing roller 14. This softens the image receiving surface 19a. At the same time, the pressing roller 14 conveys the image receiving surface 19a while pressing it against the matte surface 18. Therefore, the image receiver 19a becomes a matte surface in accordance with the matte surface 18.

When the matte surface roller 13 and the pressure roller 14 continue to rotate, the image receiving paper 19 passes over the guide plate 31 and reaches the smooth surface roller 16. During this time, the image receiving surface 19a has cooled and hardened, but is heated again by the heater 2426 and softened. The matte image receiving surface 19a is then smoothed by the smooth roller 16. By performing the matte surface treatment beforehand, the unevenness in the width direction of the image receiving surface 19a is made uniform, so smoothing can be achieved with higher perfection than when using a single smooth roller as in the past. Can be done.

Thereafter, a smooth roller 16 and a pressure roller 15 convey the image receiving paper 19 while smoothing it along the processing path 12, and then the discharge port rollers 27 and 28 convey the smoothed image receiving paper 19 from the discharge port 29. Discharge.

On the other hand, if a matte finish is desired, the switch 36 is turned downward after the power switch is turned on. This drives the solenoid 31 and rotates the guide plate 3 to position 31a. When the image receiving plate 19 is inserted in this state, the image receiving plate 19 processed by the matte surface roller 13 is transferred to the guide plate 31.
is guided to the high-bus path 34 and discharged from the discharge port 29 without being smoothed. In this way, it is possible to obtain the image receiving plate 19 which has been subjected to a matte treatment.

Note that, as shown in FIG. 2, a first heating switch 41 and a second heating switch 42 are provided separately, and the first heating switch 410
The heaters 22 and 21 may generate heat when the second heating switch 42 is turned on, and the heaters 24 and 26 may generate heat when the second heating switch 42 is turned on. According to this, gloss processing and matte processing can be performed by a combination of ON/OFF of the first heating switch 41 and the second heating switch 42, and it is possible to give variations to the processing.

In the above embodiment, the heater indirectly heats the image receiving paper 19 via the matte surface roller 13 and the smooth surface roller 16, but the heater is placed immediately before each roller in the processing path 12 to directly heat the image receiving paper 19. The receiving paper may also be heated. Further, a heating element such as a heater may be built into the roller.

Further, the present invention can also be used for glossing or matting processing of photographic printing paper instead of the image-receiving paper 19.
